Content

Description

Tree, 8-36 m high, up to 1 m dbh. Leaf-blade (5.2-)7-18(-25) by (2.3—)3—7(—12) cm, base often long attenuate with the margins of the leaf-blade curved upwards and gradually grading into the ridges of the petiole; Inflorescences often several together on one thickened node, rarely un-branched, as long as or longer than the leaves; Flowers usually with 3 together. Sepals: Petals bright yellow, or white and the upper petals with a yellow spot, or fully white, when dry yellowish, the longest one (6-)7-8(-8.5) mm long; Stamens: Ovary glabrous to hairy in apical region on 4 ribs, very rarely (in one coll.) loosely hairy all over, often semi-2-locular; Fruit 1- to often 2-locular, the second chamber often reduced and seemingly enveloped by the pericarp; Seed(s) 1 or 2.

Notes

Closely resembling 7. X. affine, and nearly always combined with that species in one taxon. The only reliable character distinguishing it from the latter species is the presence of nodal glands in the inflorescence. Due to the variability of X. affine it is difficult to identify sterile collections of both species. Differences are found in the petiole; in X. flavescens the petiole is glabrous and often bears a pair of glands, in X. affine the petiole is minutely hairy, and eglan-dular.
